My invention relates to fluorescent lamp fixtures.

One. of the objects of my invention is the provision of novel means for supporting the casing of a fluorescent lamp so that it may be swung on a horizontal aXis, on a suitable support, to different angular positions, as from a downwardly facing to an upwardly facing position.

A further object of my invention is the provi sion of novel means .by which the fluorescent lamp with its casing may be longitudinally adjusted to different positions relative to a fixed support on which it is mounted.

Still another object ofmy invention is the provision of novel means for adjustably support ing a fluorescent lamp and its casing whichis simple, strong, durable, not likely to get. out of order, is comparatively inexpensive, and which is efiicient in its operation.

The novel features of my invention are hereinafter fully described and claimed;

In the accompanying drawing which illustrates my invention,

Fig. 1 is a top view of my improved fluorescent lamp fixture.

Fig. 2 is a front view of the same, shown partly in elevation and partly broken away.

Fig. 3 is an elevation of the fixture shown mounted on a vertical supporting surface.

improvements in Fig. 4 is a vertical section on the line 4-4 of Fig. 2.

Fig. 5 is a cross section on the line 5-5 of Fig. 1.

Fig. 6 is a side view, partly in vertical section and partly in elevation of the revoluble member shown supporting the intermediate portion of the U-shaped member.

Fig. 7 is a front elevation showing in solid lines the fixture with its casing facing downwardly, and showing in dotted lines the fixture with the casing facing upwardly.

Fig. 8 is a front elevation of a modified form of the U-shaped member made of one piece of a rod.

Fig. 9 is an end view of the member shown in Fig. 8.

Fig. 10 is a side elevation of the stationary supporting member.

Similar characters of reference designate similar parts in the different views.

I designates the channel shaped casing having closed ends and supporting within it the usual fluorescent lamp tube 2.

For supporting the ends of the casing I on a longitudinal axis. there is provided a U-shaped 2 Claims. (Cl. 240-73) 2 member consisting, in the form shown in Figs.

1, 2 and 3, a cylindrical straight intermediate portion 3 having its ends rigidly fastened in one set of ends of two parallel flat plates 4, which form the arm of the U-shaped member.

Two longitudinally alined bolts 5 extend inwardly respectively through the arms 4 and the ends of the casing I. Two'washers 6 are mounted on the bolts 5 between the arms 4 and the ends of the casing I. Two nuts I on the bolts 5 respectively bear ag'ainst'two spring washers 8 on said bolts and bearing against the inner sides of the ends of the casing I, thus pivotingthe ends of the casing with a frictional resistance on the bolts 5 between the arms 4. The casing I is, thereby, pivotally mounted on its longitudinal aXis, so as to be retained in the diiferentpositions to 'which it. may be swung around its axis.

For supporting the U-shaped member, the following. described mechanism is employed.

A supporting member havinga horizontal forwardly extending. cylindrical portion 9, Fig. 10, has at its rear end means consisting .of a radial portion I9 provided therethrough with two screws II for fasteningto a vertical surface, as a wall I2, Fig. 3. I

Said cylindrical portion 9 has, spaced from its front end, a peripheral abutment I3 provided with an'arcuate forwardly'extendin'g lip I4.

7 A horizontal member I5, Fig. 6, has a rear end tubular portion circumferentially oscillatively revolubly mounted'on the cylindrical portion 9, and is provided at its rear end with an arcuate lip I6, operatively disposed in the transverse plane of the abutment lip I4, against opposite edges of which the lip I6 is adapted to strike, when the revoluble member I5 is oscillated.

The revoluble member I5 is provided, forward of the cylindrical portion 9, with a transverse opening comprising a longitudinal slot I! extending rearwardly from the front end of the revoluble member I 5, and adapted to receive therein transversely thereto, the straight intermediate portion 3 of the U-shaped member.

The intermediate portion 3 is adapted to be longitudinally adjusted in the slot I! to different selected positions. For rigidly supporting the intermediate portion 3 in its adjusted positions in the slot H, the revoluble member has extending through it, forward of the intermediate portion 3, across the slot I1, a clamping screw I8, Figs. 1, 2, 3 and 6.

0n loosening the clamping screw I8, the intermediate portion 3 of the U-shaped member may be longitudinally adjusted to a desired position, after which the clamping screw I8 is tightened, holding the U-shaped member rigidly fastened to the revoluble member 15.

If it is then desired to swing the U-shaped member, together with the casing I, on the cylindrical portion 9 of thi fixed supporting member, from the horizontal downwardly facing position, shown in Fig. 7, it may then be swung in the direction indicated by the curved arrow in Fig. 7. If the combined circumferential width of the lips 14 and I6 is 180 degrees, as shown in Fig. 5, the U-shaped member together with the casing i may be swung 180 degrees, so as to have the casing 1 face upwardly.

The intermediate portion 3 of the'U-shaped member may be longitudinally adjusted in the slot I! to suit the particular requirements of the use to which it is to be put.

In Figs. 8 ar d 9, a modified form of the L'- shaped member is shown, in which form, the member is composed of a single piece of material, as a rod, the free ends of the arms, designated by 4', being flattened and each end having therethrough a hole 19.

In the use of this modified form, the bolts 5 are respectively inserted through the holes 19, and the other parts assembled as with the first described form of the invention.

Other modifications of my invention, within the scope of the appended claims, may be made without departing from the spirit of my invention.

What I claim is:

1. In a fluorescent lamp fixture, in combination, a channel shaped fluorescent lamp casing having closed ends, a U-shaped member having between its arms a longitudinal straight intermediate portion, means pivotally supporting on a longitudinal axis the ends of said casing to and between said arms, a supporting member having means at its rear end adapted for attachment to a support and having a horizontal forwardly extending cylindrical portion having spaced from its front end a peripheral'abutment with a forwardly extending arcuate lip, and a revoluble oscillative member having a near end tubular portion circumferentially revoluble on said cylindrical portion and having projecting rearwardly an arcuate stop lip in the transverse vertical plane of said, abutment lip opposite edges of which it is adapted to strike when said revoluble member is oscillated, said revoluble member having forward of said cylindrical portion a transverse opening through which extends and is longitudinally adjustable said intermediate portion of said U-shaped member, said revoluble member having releasable means for rigidly fastening said intermediate portion in its adjusted longitudinal position, whereby said U-shaped member with said casing supported, thereby may be oscillatively circumferentially swung with said revoluble member on said cylindrical portion as an axis to difierent angular positions.

. 2. In a fluorescent lamp fixture, incombination, a channel shaped fluorescent lamp casing having closed ends, a U-shaped member having between its arms a longitudinal straight intermediate portion, means pivotally supporting on a longitudinal axis the ends of said casing to and between said arms, a supporting member having means at its rear end adapted for attachment to 'a support and having a. horizontal forwardly extending cylindrical portion having spaced from its front end a peripheral abutment with a forwardly extending arcuate lip, and a revoluble oscillative member having a rear end tubular portion circumferentially revoluble on said cylindrical portion and having projecting rearwardly an arcuate stop lip in the transverse vertical plane of said abutment lip opposite edges of which it is adapted to strike when said revoluble member is oscillated, said revoluble member having through its front end a longitudinal slot through which extends and is longitudinally adjustable said intermediate portion of said U -shaped memher, said revoluble member having releasable means for rigidly fastening said intermediate portion in its adjusted longitudinal position, whereby said U-shaped member with'said casing supported thereby may be 'oscillatively circumferentially swung with said revoluble member on said cylindrical portion as an axis to difierent angular positions.
